A system, method, and computer program product is provided for secured, encrypted transaction processing. The method includes receiving a transaction request initiated by a first computing device associated with a first user and/or a second computing device associated with a second user. The transaction request includes a first user token including a first token identifier and a first account balance encrypted with a public key of the first user. The transaction request also includes a transaction value and a second user token including a second token identifier and a second account balance encrypted with a public key of the second user. The method includes generating a new first user token including a new first account balance encrypted with the public key of the first user and a new second user token including a new second account balance encrypted with the public key of the second user.
Legal claims defining the scope of protection, as filed with the USPTO.
4. The computer-implemented method of claim 1, wherein the transaction value is encrypted with the public key of the public/private key pair associated with the first user.
5. The computer-implemented method of claim 1, wherein the transaction request is digitally signed with a private key of the public/private key pair associated with the first user, and wherein verifying the transaction request comprises decrypting, by the transaction processing system, the transaction request using the public key of the public/private key pair associated with the first user.
6. The computer-implemented method of claim 5, wherein the transaction request is further digitally signed with a private key of the public/private key pair associated with the second user, and wherein verifying the transaction request further comprises decrypting, by the transaction processing system, the transaction request using the public key of the public/private key pair associated with the second user.
9. The system of claim 7, wherein the transaction value is encrypted with the public key of the public/private key pair associated with the first user.
10. The system of claim 7, wherein the transaction request is digitally signed with a private key of the public/private key pair associated with the first user, and wherein verifying the transaction request comprises decrypting the transaction request using the public key of the public/private key pair associated with the first user.
11. The system of claim 10, wherein the transaction request is further digitally signed with a private key of the public/private key pair associated with the second user, and wherein verifying the transaction request further comprises decrypting the transaction request using the public key of the public/private key pair associated with the second user.
14. The computer program product of claim 12, wherein the transaction value is encrypted with the public key of the public/private key pair associated with the first user.
15. The computer program product of claim 12, wherein the transaction request is digitally signed with a private key of the public/private key pair associated with the first user, and wherein verifying the transaction request comprises decrypting the transaction request using the public key of the public/private key pair associated with the first user.
16. The computer program product of claim 15, wherein the transaction request is further digitally signed with a private key of the public/private key pair associated with the second user, and wherein verifying the transaction request further comprises decrypting the transaction request using the public key of the public/private key pair associated with the second user.
